Summarize a PDF — study summary, then a quiz from the same file.
Lecture slides, textbook chapters and past papers usually arrive as PDFs you never reopen. Skoolskill reads the PDF, condenses it into a clear study summary, and then quizzes you on it — so the file becomes recall practice instead of another download in your folder.
A summary’s value isn’t the summary — it’s what you remember afterwards. Most “summarize a PDF” tools hand you a tidy paragraph and stop there, which is exactly the page you skim once and forget. Skoolskill condenses the PDF and then quizzes you on it, so reading the file turns into recall practice instead of a neat block of text.
That summarize-then-test loop is the whole design. Reading is passive; being tested is active, and active recall is what survives to exam day.
How it works, step by step
Open Skoolskill and upload your PDF — slides, a chapter, a past paper.
The AI reads it (digital text directly, scanned pages via OCR).
It produces a structured summary: key points, definitions, the main argument.
Ask for a tighter one-paragraph version or a more detailed outline.
Tap to generate a quiz on the summarized material.
Missed points roll into spaced repetition for the next few days.
Time to first result: under a minute from upload to a finished summary.

For plain recall on the same file, the flashcard maker builds spaced-repetition cards from it; for a general overview of the format, see the AI summary generator.
Choosing how tight the summary is
The same PDF can become three summaries depending on what you’re doing. Skimming before a lecture? Ask for the one-paragraph version that captures the argument so you walk in oriented. Revising properly? The default half-page of bullets plus key definitions is the workhorse — short enough to re-read in two minutes, structured enough to test yourself against. A genuinely hard chapter? The detailed outline keeps sub-points so nothing important is dropped.
What it won’t do
It won’t summarize a PDF that is mostly diagrams or images — there’s too little text.
It won’t capture everything; treat the summary as a study aid and check it against your specification.
It won’t help much with problem-based maths — there, worked practice beats a summary.
It won’t guarantee a grade. It makes condensing-and-testing fast; doing it daily is still your job.

Read the summary, then generate a quiz on it.
Let missed points return through spaced repetition.
Upload the PDF — lecture slides, a scanned chapter, a revision guide — and Skoolskill reads it and produces a structured study summary: key points, definitions and the main argument in plain language. A typical chapter-length PDF is summarized in well under a minute.
Does it read scanned PDFs, not just digital text?
Yes. Text-based PDFs are read directly; scanned or image-only PDFs are run through OCR page by page, so a photographed textbook saved as a PDF still works. Clean, printed text gives the sharpest summary.
Can it quiz me on the PDF afterwards?
Yes, and that's the point. From the same PDF it builds a short quiz on the summarized material, so you don't just read the summary — you're tested on it. Summarize-then-quiz holds information far better than reading a PDF once.
How long can the PDF be?
Short documents summarize in one pass. Very long PDFs are handled in sections; for a whole textbook, summarize a chapter at a time so each summary stays tight enough to revise from and quiz against.
What kinds of PDFs work best?
Content-heavy ones: lecture slide decks, textbook chapters, class handouts, revision guides and past papers. PDFs that are mostly diagrams or images summarize poorly because there is little text to condense.
How is this different from a generic PDF summarizer?
Most PDF summarizers stop at the summary. Skoolskill turns it into studying: the summary flows into a quiz and into spaced repetition, so a missed point comes back over the next few days instead of vanishing.
What does it cost?
Free to start, no credit card — you can upload PDFs and generate summaries and quizzes on the free tier. The paid tier at about £6.99 / $6.99 a month adds longer upload sessions for heavy revision periods.
